How hard is it to chnage the jexts on a sportsman twin carburated model. All I need to do is get at the bowl and swap jets, do I have to remove the carb and what involved in that? I think that stock jet on the 700 is a 155, I orderd a 160 as I had it out in the cold yesterday (28 degrees) and it was backfiring occasionally when I juiced.

I was hoping it was like some otther models that have access to the float bowl while the carb is on the machine.

Thanks for the help.

the main jet is in the jet block under the diapham and not sure if you can get to it thru the bowl or not, but would guess yes. what year is the bike? looked at an 04' 700 and depending on when it was made it had a 155 or a 157.5 in it.

 

pull th 4 screws to remove the bowl where the float is and you will see the main jet. Use a good flat blade screwdriver to remove the old jet and to install new jet. Do not overtighten.
All this can be done without removing the carb. Just remove airbox and loosen carb and you should be able to turn it to get at the bowl.

 

I have a 2004 SP700 carb and rejetted a couple of years ago using a jet kit from somebody-or-other. Removing the carb is inconvenient but once you've done it the process is straightforward, just awkward. Removal is "up" from under the seat. As I recall there are some brackets and other hardware that are in the way and must be removed.

Once it's back on the engine, you'll need a very short flat blade screwdriver to adjust the idle screw. I took a short flatblade with a clear plastic handle and cut off all of the handle that protruded past the metal shaft of the blade. The result was a little flatblade only a couple of inches long. It barely fits but does the job, and now lives in the little toolbox under the seat.

Hope this helps!
